| 摘 要： | 通过对黄土高原典型小流域地貌参数的分析计算,应用地貌单位线理论,分析了地貌参数与产沙的关系,揭示了地貌特征对产沙的影响,并把地貌因子引用到暴雨洪水产沙计算模型中,有效地解决了无水文资料地区的产沙分析评价和预测等问题,为开展区域水土保持研究和治理提供了新途径.

| Abstract: | In the research of sand-producing mechanism in a watershed, people pay more attention to the effects of precipitation intensity and vegetation than topographic from. Based on the analyses and calculations of topographical parameters of typical small watersheds in loess plateau and also on topographical-unit line theory, this paper reveals the impact of topographical feautres on sand produce and tries to apply them into the sand-producing model in a rainstorm or flood. |
